Answer:

The main ingredient of cells is water. Water is needed to maintain homeostasis. Cells are also made up of macromolecules—nucleic acids, lipids, proteins, carbohydrates. These macromolecules help maintain a cell's structure, help cells communicate with each other, aid in energy storage, etc.

1.) spindle fibers and centrioles form

2.) chromosomes align on metaphase plate

3.) chromosomes move to opposite poles

4.) two identical nucleotides form

Mitosis is important because it is responsible for the growth of is responsible for human development.

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

HELP ASAP<br> Punnett Squares
pashok25 [27]

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.
